You know... I thought they weren't repairable because data was getting thrown away [here](https://github.com/mozilla/openbadges/pull/838/files#L0L404), but I think they could be fixed. `info.structures.assertion` doesn't contain the expanded badge or issuer data, but I guess it still has the badge data url, which in turn has the issuer data url. Maybe we can resubmit that to the badge validator to rebuild the `info` to send in to `normalizeAssertion`...
